IMPORTANT Cycle Tracker is a tracking and educational tool, not a medical device. Predictions are statistical estimates calculated from the cycle history you enter — they are not a diagnosis and must not be used as a method of contraception or to rule out pregnancy. Always speak to your doctor before making any medical decision.
